Video wall and mullion elimination lens thereof

Abstract

An exemplary video wall includes two display panels and a polygonal mullion elimination lens. Each of the display panels includes a main body and a bezel surrounding the main body. The polygonal mullion elimination lens includes a central first concave surface configured to reflect internal light incident thereon, two flat surfaces respectively attached to the main bodies of the display panels, a central second concave surface opposite to the first concave surface, and two lateral surfaces each connecting between a corresponding one of the flat surfaces and the second concave surface. Portions of light emitted by the main bodies of the display panels can enter the mullion elimination lens via the flat surfaces.

What is claimed is: 
     
       1. A video wall comprising:
 at least two display panels, each of the at least two display panels comprising a main body and a bezel surrounding the main body; and 
 at least one polygonal mullion elimination lens comprising:
 a central first concave surface configured to reflect internal light incident thereon; 
 two flat surfaces respectively attached to the main bodies of two adjacent of the at least two display panels, thereby allowing portions of light emitted by the main bodies of the two adjacent display panels to enter the at least one mullion elimination lens via the flat surfaces; 
 a central second concave surface opposite to the first concave surface; and 
 two lateral surfaces each connecting between a corresponding one of the two flat surfaces and the second concave surface; 
 wherein a portion of the light that enters the at least one mullion elimination lens via each of the flat surfaces penetrates a corresponding lateral surface, and wherein the remaining portion of the light that enters the at least one mullion elimination lens via each of the flat surfaces is respectively reflected by the corresponding lateral surface to the first concave surface, and by the first concave surface before it passes out from the at least one mullion elimination lens through the second concave surface. 
 
 
     
     
       2. The video wall as described in  claim 1 , wherein the at least one mullion elimination lens is integrally formed of transparent material. 
     
     
       3. A mullion elimination lens for eliminating a mullion of a video wall, the video wall comprising at least two display panels, each of the at least two display panels comprising a main body and a bezel surrounding the main body, the mullion elimination lens comprising:
 a central first concave surface for reflecting internal light incident thereon; 
 two flat surfaces respectively attached to the main bodies of two adjacent display panels of the at least two display panels, thereby allowing portions of light emitted by the main bodies of the two adjacent display panels to enter the mullion elimination lens via the flat surfaces; 
 a central second concave surface opposite to the first concave surface; and 
 two lateral surfaces each connecting between a corresponding one of the two flat surfaces and the second concave surface; 
 wherein a portion of the light that enters the mullion elimination lens via each of the flat surfaces penetrates a corresponding lateral surface, and wherein the remaining portion of the light that enters the mullion elimination lens via each of the flat surfaces is respectively reflected by the corresponding lateral surface to the first concave surface, and by the first concave surface before it passes out from the mullion elimination lens through the second concave surface. 
 
     
     
       4. The mullion elimination lens as described in  claim 3 , wherein the mullion elimination lens is integrally formed of transparent material. 
     
     
       5. A video wall comprising:
 two display panels, each of the two display panels comprising a main body and a bezel surrounding the main body; and 
 a polygonal mullion elimination lens comprising:
 a central first concave surface configured to reflect internal light incident thereon; 
 two flat surfaces respectively attached to the main bodies of the two display panels, thereby allowing portions of light emitted by the main bodies of the two display panels to enter the mullion elimination lens via the flat surfaces; 
 a central second concave surface opposite to the first concave surface; and 
 two lateral surfaces each connecting between a corresponding one of the two flat surfaces and the second concave surface;
 wherein the mullion elimination lens provides light paths for a portion of the light that enters the mullion elimination lens via each of the flat surfaces to penetrate the corresponding lateral surface; and for the remaining portion of the light that enters the mullion elimination lens via each of the flat surfaces to be reflected by the corresponding lateral surface to the first concave surface, and to be reflected by the first concave surface and pass out from the mullion elimination lens through the second concave surface. 
 
 
 
     
     
       6. The video wall as described in  claim 5 , wherein the mullion elimination lens is integrally formed of transparent material.
